However, while that is protected by the # watchqueue lock, new watchqueue entries aren't actually added under that # lock at all: they use the pipe->rd_wait.lock instead, and looking up # that pipe happens without any locking. # # The watchqueue code uses the RCU read-side section to make sure that the # wqueue entry itself hasn't disappeared, but that does not protect the # pipe_info in any way. # # So make sure to actually hold the wqueue lock when posting watch events, # properly serializing against the pipe being torn down. # # Reported-by: Noam Rathaus # Cc: Greg KH # Cc: David Howells # Signed-off-by: Linus Torvalds # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 353f7988dd8413c47718f7ca79c030b6fb62cfe5 # < make -s -j 120 ARCH=mips O=/kisskb/build/linus_32r2_defconfig_mips-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/mips-linux/bin/mips-linux- 32r2_defconfig ./.config.32r2_defconfig:94:warning: override: CPU_BIG_ENDIAN changes choice state .config:93:warning: override: CPU_BIG_ENDIAN changes choice state # < make -s -j 120 ARCH=mips O=/kisskb/build/linus_32r2_defconfig_mips-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/mips-linux/bin/mips-linux- help # make -s -j 120 ARCH=mips O=/kisskb/build/linus_32r2_defconfig_mips-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/mips-linux/bin/mips-linux- olddefconfig # make -s -j 120 ARCH=mips O=/kisskb/build/linus_32r2_defconfig_mips-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/mips-linux/bin/mips-linux- /kisskb/src/arch/mips/boot/dts/img/boston.dts:128.19-178.5: Warning (pci_device_reg): /pci@14000000/pci2_root@0,0,0: PCI unit address format error, expected "0,0" Completed OK # rm -rf /kisskb/build/linus_32r2_defconfig_mips-gcc11 # Build took: 0:00:48.201150
